Paul Riseborough 040639837e EKF: Use common timeout test for reporting deadreckoning 
Use a parameter to set the time-out threshold
Use a class variable for the time-out flag

Paul Riseborough 5fb24c3032 EKF: Reduce EKF prediction delta time jitter 
Make the target EKF rate an integer multiple of the IMU rate. This slightly increases the average prediction time step for the EKF from just over 10msec to 12msec, but the variation reduces significantly which makes filter tuning more deterministic.
Improve the algorithm used to adjust the collection time criteria to reduce jitter in the correction.
